Title: Synthetic polyisocyanate polymers and methods for their preparation
IPC: C08G18/80
Filed: 1951-08-29
Abstract: Polymers are produced by reacting a masked polyisocyanate, which is the adduct of a polyisocyanate and a tertiary alcohol, secondary aromatic amine, mercaptan, lactam, monohydric phenol, imide or compound containing enolizable hydrogen, with a substance having a plurality of radicals containing reactive hydrogen selected from the amide, ureylene, carbamic, hydroxyl, carboxyl or amino groups, particularly the elastomeric diisocyanate modified polyesters and polyesteramides described in Specifications 694,978, 694,982, 696,449 and 696,450.  The adducts used are described in Specifications 701,548, 701,459, 701,711, 701,712, 709,288, 710,122 and 716,194. The use of the adducts, which dissociate at raised temperatures, enables the rate of reaction of the polyisocyanates, and hence of the curing and crosslinking of the elastomers refined to, to be controlled.  The Specification lists many examples of the following groups of substances, in addition to the elastomers referred to, which may be reacted with the masked isocyanates to give polymers:-polyhydric alcohols, polyamines, polycarboxylic acids, amino alcohols, amino-carboxylic acids and hydroxy-carboxylic acids. In examples: (13) 100 parts of a rubber-like polymer which is a polyester of acid number 3.5 and hydroxyl number 58.6 from adipic acid, ethylene glycol and propylene glycol modified with 4.41 diphenylene diisocyanate, is mixed on a rubber mill with 8.19 parts of the adduct of epsilon caprolactam and 4.41 diphenylene diisocyanate.  Test sheets were heated at 248 DEG F. for 26 hours and then press cured for 35 minutes at 300 DEG F.  (14) As in 13 but using 9.45 parts of the adduct from 2-mercaptobenzthiazole and press curing for 70 minutes at 300 DEG F.  (15) As in (14) but using 8.48 parts of the adduct from succinimide.  (16) As in (13) but using a polyester modified with 1.5 naphthalene diisocyanate, 12.2 parts of the adduct from 1.5 naphthalene, diisocyanate and diethyl malonate, heating for 2 hours at 300 DEG F. and press curing for one hour at 300 DEG F.  Figures are given for the mechanical properties of the cured rubbers of the examples and comparative figures for the degree of cross-linking after 2 and 5 days of the uncured rubber of examples 13, 14 and 15 in the presence of masked isocyanates and of the uncured rubber of example 13 in the presence of 4.41 diphenylene diisocyanate.

Title: Improved method and apparatus for applying decorative aggregate to surfaces
Inventor: SMITH WILLOUGHBY ARTHUR
IPC: B05D1/02
Filed: 1968-05-02
Abstract: 1,249,157. Ornamenting. W. A. SMITH. 25 July, 1969 [2 May, 1968], No. 20749/68. Heading B6G. Aggregate is applied to a surface, e.g. of walls, ceilings, pillars, by (1) delivering fluid adhesive along a pipe from a container to a spraying tool and discharging a stream of the adhesive towards the surface, (2) delivering aggregate from another container into a passage connected to the tool, driving the aggregate along the passage by gas pressure, reducing the initial velocity of the aggregate prior to discharge from the tool, and discharging the aggregate and the gas from the tool in separate streams, and (3) directing the stream of aggregate towards the surface so as to meet the stream of fluid adhesive material so that the aggregate is coated with adhesive before reaching the surface. As shown in Fig. 1, a stream 156 of atomized liquid adhesive is discharged from spray gun 18 of tool 12 by manually drawing trigger 88 rearwardly so that adhesive 27 is forced under the pressure in container 22 through pipe 28 to the nozzle of spray gun 18 where the liquid is entrained in a stream of air from pipe 38 and discharged through the nozzle. Trigger 88 is then moved rearwardly through a second stage to allow air under pressure to pass through outlet 68 of pipe 70 whereby granular aggregate 50 is entrained in the stream of air passing through pipe 64 and fed into aggregate discharging part 16 of the tool. The velocity of the stream of aggregate is decreased as a result of expansion in part 16 and obstruction by the elbow formation of part 16. A lip deflector 152 deflects the air stream upwardly but has no substantial effect on the stream 158 of aggregate which issues in alignment with the forward part 136 of the elbow.

Abstract: 212,900. Relay Automatic Telephone Co., Ltd., (Assignees of Betulander, G. A.). March 12, 1923, [Convention date]. Automatic exchange systems.-In systems in which an incoming line IL is connected to an outgoing line UL by means of cross-bar selectors, the connecting relays AR in each connecting apparatus AK mutually control their circuits, and auxiliary relays HR corresponding to the marking relays MR similarly mutually control their circuits, so that double connections are prevented in the event of simultaneous calls. The incoming lines IL are arranged in groups G each having a marking relay, and each set of contacts KG is closed by operation of the corresponding marking and connecting relays MR, AR. The marking relay is released upon completion of the connection, which is maintained by the connecting relay only. Specifications 141,005 and 187,580 are referred to. Circuit connections. When a call occurs on line IL1, line relay LR1 closes circuit 2 for relay HR1 in the group G1, which locks over circuit 3 in series with relay DR, which opens the energizing circuits of the relays HR. Should calls ocour simultaneously in the groups G1, G2, relay HR1 opens the circuit of relay HR2 so that only one call is effective. Relay DR operates relay KR1 if the line UL1 is idle, whereupon marking relay MR1 energizes over circuit 5, connecting the marking circuits MS of the lines of the group G1 to the connecting relays AR of the apparatus AK1. Relay AR1 energizes over winding AL in a circuit 6, and connects the lines IL1, UL1 over contacts KG1. Relay FR1 energizes over the-calling loop and closes a holding circuit 7 over winding HL of relay AR1 and cut-off relay UR1, the latter releasing line relay LR1 and the relays used for establishing line relay LR1 and the relays used for establishing the connection. Line UL1 is marked busy by the opening of contacts K. In the case of simultaneous calls in the group G1, only one is effective since relay AR1 opens the circuit of relay AR2. In a modification, the incoming line relays are replaced by calling relays common to groups of lines, and the marking circuits include special relays which are connected to the lines of different groups by means of the auxiliary relays HR and control the circuits of the connecting relays AR.
